Pulley A has a weight of 30 lb and a centroidal radius of gyration k_B = 0.6 ft. Determine the speed of the 20-lb crate C at the instant s = 10 ft. Initially, the crate is released from rest when s = 5 ft. The pulley at P "rolls" downward on the cord without slipping. For the calculation, neglect the mass of this pulley and the cord as it unwinds from the inner and outer hubs of pulley A.
